1. The group 1 and 2 can be selected by DZFM2-0 bits.
2. This pin becomes OVF pin if OVFE bit is set to “1”.
3. All input pins except internal biased pins should not be left floating.

Power-Down & Reset Pin
Large external capacitor around 2.2µF is used to reduce power-supply noise.
When the input data of the group 1 follow total 8192 LRCK cycles with “0” input data,
this pin goes to “H”.
18k +/-1% resistor to PVSS externally.
“L”: Master mode or Slave mode, “H”: Slave mode
This pin should be connected to DVSS.
“L”: 4-wire Serial, “H”: I
When “L”, the AK4586 is powered-down, all output pins go to “L” and the control
registers are reset to default state. If the state of CAD1-0 changes, then the AK4586
must be reset by PDN.
